Why Magnets may Repel Mosquitoes and other Predatory
... Mosquitoes can sense even the tiniest changes in this electrical current, down to one-billionth of a volt. Compare this with two AA batteries that are connected to each other and extended 1,000 miles (1,600 kilometers) apart. A Mosquito could effectively detect if any of these batteries were to expi ...

... material such as glass or rubber does not ordinarily allow any passage of charges through it. At the other extreme, an electrically conducting material such as copper will offer very little resistance to the motion of charges, so electric forces acting on it readily produce a current of charges. (Mo ...

The Electric Field due to a Point Charge
... An electric conductor is a material in which electric charge can move easily. Metals such as copper, aluminum and iron are conductors. Conductors have “free electrons” which move easily. An electric insulator is a material in which electric charge cannot move easily under ordinary conditions. Exampl ...

Static electricity

Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.A static electric charge is created whenever two surfaces contact and separate, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shock–more specifically, an electrostatic discharge–is caused by the neutralization of charge.
